DRAW-BAR FOR STREET-CARS.

SPECIFICATION forming part of Letters Patent No. 247,508, dated September 2'7, 1881.

Application filed November 25, 1879.

To all whom it may concern Be it. known that I, BERNARD MODEVITT, of Chicago, Cook county, State of Illinois, have invented a new and useful Improvement in Draw-Bars for Street-Oars, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a plan 5 Fig. 2, a side elevation; Fig. 3, a central vertical longitudinal section. Figs. 4, 5, and 6 representa modification in the form of construction, to adapt it for attachment to an ordinary draw-bar.

This invention is primarily designed to be used with street-cars with which no tongue is used; and it consists in providing the draw-bar with a removable hook to receive the evener or whififletree, so that such hook can be easily replaced when worn or broken; in providing the head of the draw-bar proper with a countersink, and a slot to receive the head of a short secondary bar, which carries the hook mentioned, and in providing such secondary bar with a support for the evener, as hereinafter fully set forth.

In the drawings, A represents a draw-bar.

. The lower part of the head D is provided with a recess or countersink, a, and the upper part has a slot or opening, I), in one side, communieating with the hole through such upper part. 0 is a short bar, which may be called a secondary draw-bar. It has a head, 0, the ends of which fit, respectively,into the countersink a and the hole in the upper part of the head of the draw-bar A, and when the parts are in use this head 0 serves the purpose of a draw pin. There is a hole through the center of this head 0, through which, and through a hole in the lower part of the head D, a bolt, d, passes,

held in place by a key, 6, as shown in Figs. 2

and 3. The head 0 might be made solid, with a smaller projection on the lower end to take the place of the pin (1.

B is a hook, made separate from the bar 0. It has a shank, f, which passes through the bar 0, and it is firmly secured to the bar by means of a key, 9, which passes through a hole in the shank 1).

his a support for the evener. It is cast with the bar 0. On the top of this support h is a piece of rubber, leather, or other suitable material, t, which prevents the evener from wearing by contact with the support h. This piece i can be secured to the support It by means of bolts, and when worn can be replaced.

The evener or whiffletl'ee, being provided be well connected. directly to the head of the draw-bar A. The secondary bar 0 and hook B furnish a convenient way of attaching the evener or whiffletree.

In Figs. 4, 5, and 6 I have shown a variation in the construction of the bar 0, in which this bar, instead of having a head, 0, (shown in the other figures,) has an ordinary eye, n, adapted to receive a bolt. This form is adapted to be used with an ordinary draw-bar which does not have the countersink a and ,the slot 12 in the head, and it can be connected with such a draw-bar by inserting the eye it between the two parts of the head of such common drawbar and securing the same by an ordinary bolt or pin. This piece 0 can be swung around out of the way when the cars are run together, as is common when not in use.

A long drawbar made from a single piece could be provided with a removable hook, B, but if it projected as far as I think it ought to in front of the platform it would be in the way when the cars were run together.

What I claim as new, and desire to secure by Letters Patent, is as follows:

1. Adetachable draw-bar, (J, provided with the removable hook B, for the attachment of an eye or ring on the evener or whiffletree, and with a support or seat arranged in front of said hook, on which the evener or whiffletree rests, substantially as described.

2. The combination, with a draw-bar, A, of an attachable and detachable secondary drawbar, 0, provided with the hook B, to receive an eye or ring on the evener or whiffletree, and with the support or seat h, arranged in front of said hook, on which the evener or whiffletree rest-s, substantially as and for the purpose described.

3. The combination, with a draw-bar, A, of

a laterally-swinging attachable and detachable secondary draw-bar, O,'provided with the removable hook B, to receive an eye or ring on the evener or \vhifiietree, and with the support or seat h, arranged in front of the hook, and on which the evener or whiffletree rests, substantially as and for the purpose described.

4. A draw-bar, A, having a head provided with a countersink, a, and a slot or opening, I), in combination with the secondary bar 0, hav- 1o ing a head, 0, adapted to enter the countersink a, and slot 1), substantially as specified.
